check this sit out 400 watt HPS and MH for as ow as 8 dollars check it out u guys they have ballasts CLFS fluros wat ever u guys want even LEDS check it out
Those are only bulbs, no ballast, just so you know.
Not like the econolight $20 150w hps's that come with everything but a cord but for any bulbs they are a good source for sure if you get enough to make the shipping costs make sense.
